2024 Mercedes-AMG G63 | UK Review 

Considered from afar, you might be inclined to wonder if Mercedes has lost its way when it comes to satisfying customer demand. The latest four-cylinder C63 E Performance, launched to near-universal consternation, is an obvious example. But in May the firm revealed that it was binning an entire EV platform because the future models that were intended to sit atop it – namely the replacement EQE and EQS – hadn’t got anywhere near Mercedes’ projected sales volume in their current format. A symptom of the wider battery-electric slowdown? Sure. But also potentially of a company paying too little attention to what its buyers actually want, rather than blithely hoping to sell them what they might conceivably need. 

Considered from much closer up – i.e. within arm’s length of the latest Mercedes-AMG G63, a car that retains both its 585hp 4.0-litre twin-turbo V8 and the self-assurance of a WWE wrestler – and you realise that assessment is probably complete cobblers. The newest variant of the famed Geländewagen, whether you personally like it or not, seems like nothing less than the perfect manifestation of its buyers’ wettest dreams. It is as loud and as able as a helicopter gunship and as swanky and nice-smelling as a Bel Air florist. It attracts the attention of passersby like a Banksy mural and costs the earth to buy and run. You’ll probably hate yourself for liking it. 

Although it’s fair to say that the acceptable window for liking the G63 is larger than ever. If there is a lesson to be drawn from the lacklustre sales performance of models like the EQE and EQS (and let’s assume Mercedes is drawing one) it is that cars devoid of character are hard to like. The modern G-Wagen, partly as a factor of its long heritage and for making no real-world sense when equipped with side exit exhausts, has character gushing from its wing mirrors. Granted, some of this character, when restricted to Kensington High Street, might seem objectionable. But when measured against a neighbour’s VW ID.4 it’s very hard not to drop to your knees and thank goodness that you live in an age where someone can still strap a V8 to a separate chassis and call it gold. 

Which isn’t to suggest that the G-Class isn’t moving with the times. Indeed, this change in generational nomenclature has come about in just six years – prior to that, it took Mercedes the best part of three decades to move its body-on-frame mountain closer to the present day. The main thrust of the recent overhaul has gone into perfecting the Mercedes-Benz G580 with EQ Technology – or the electric G-Wagen to you and me. The early word suggests it’s pretty good. But for as long as the G63 exists, any other version of the G-Class is merely a sideshow. Globally speaking, this is the big seller and still very much the temperature setter. 

Good, then, that it’s the best iteration yet. This is partly to do with the introduction of some new tech, although it’s notable (especially in the wake of the C63) the extent to which Mercedes-AMG has not allowed any of it to significantly muddy the G-Class water. Had it taken the wrong approach, the firm might have run wild with what a G63 could be. Instead – and in stark contrast to its efforts elsewhere – the idea of what it should be seems to have remained in sharp focus. So you get newfangled mild-hybrid status – i.e. 48-volt architecture and an integrated starter-generator – but you won’t really notice its modest assistance when moving. Or not in a way that shifts the spotlight away from the surly V8, which has somehow retained a variation of the Thunder-God soundtrack we thought had been nixed for good by particulate filters and the nanny state. 

Immersing yourself in the noise and the improbable surge of the G63 is still very much part of the core experience. With 627lb ft of torque ultimately on tap, there’s no practical requirement to go rooting around the footwell with your size nines  – and yet, giddy as a bishop at the seaside, you’ll often find yourself ankle-deep in the fun stuff. It is precisely the same guilty pleasure being chased by various V8-powered Land Rover Defenders, although to drive the G-Class is to be reminded of where the benchmark for SUV-based silliness currently resides.  The forthcoming OCTA has its work cut out emulating the G63’s scurrilous fun factor. 

Particularly as its rival has stolen a march on the hydraulic interlinking of its adaptive dampers. The lean-suppressing characteristics of the AMG Active Ride Control system has permitted the removal of the G-Wagen’s conventional anti-roll bars, and obviously provided a much greater bandwidth for suspension tuning – but, again, there is nothing crude or tactless about the implementation. In Comfort mode, the G63 still barrels enigmatically up a road on 22-inch wheels, no longer defined by its separate chassis, yet plainly in possession of one. It meanders heftily but not inconsiderately over bumps, like Ross Kemp negotiating a farm stile, but it’s the progressive and impressively subtle management of the high-sided body that distinguishes this G-Class from any other. 

Fundamentally, the pay-off is a better driving – i.e. more controllable and cleverer – G63. But even in Sport mode, the effect is refreshingly low-key. So while it changes direction more adeptly, we’re not talking about the sort of heightened dynamism that would feel at odds with either the G-Wagen’s modus operandi or its 2,753kg kerbweight: this is the same hulking, tarted-up breeze block that you’d hesitate to really throw down a B road. It’s just nicer and less stressful to steer when pressing on. And even when it clearly is making an effort, it generally resists the tedious ‘sporty’ tag that most fast SUVs subscribe to. It very much wants to be burly and boisterous, even as it’s being slightly pointier and quicker to turn. It manages to pull off both – and to an extent that no previous G63 managed. 

Otherwise, it’s mostly as it was. We didn’t get the chance to sample it off-road, but there’s no reason to think its powers are waning. Quite the opposite. The interior has been treated to a mild overhaul, mostly centred on the installation of an updated (and much crisper) 12.3-inch display which is also a touchscreen for the first time. As Mercedes has never done infotainment controllers well, this is a good thing – especially as the G-Wagen’s utilitarian pedigree means it retains many more physical buttons than most Mercedes. Probably its maker doesn’t tread the line between soft-touch luxury and squared-off ruggedness as cleverly as Land Rover – but why would it bother? The LED-lit, Nappa leather-clad strategy has manoeuvred the G63 into a position where its admirers will patiently queue for the chance to hand over £200k to own one. No wonder its genuine enhancements are made to seem incremental and in keeping with a car that people like just as it is. Mercedes makes it look easy. It should try it more often.
